Description of a New Species of Spiny Solanum (Solanaceae) from Rocky Outcrops of Northeastern Brazil, with Modeling of Its Environmental Suitability.

Rocky outcrops surrounded by vegetation in northeastern Brazil form special ecosystems of high species richness and endemism and represent priority areas for biodiversity studies and conservation measures. Floristic surveys of rocky outcrops in the State of Ceará resulted in the identification of a new species of Solanum from the Thomasiifolium clade. Its morphological description, geographic distribution, habitat, ecology, informal conservation status, and environmental suitability models are provided and discussed. [ABSTRACT FROM AUTHOR]
